Split personalities: We like some science, but not all of it

Split personalities: We like some science, but not all of it

We modern folk are in a bind. We embrace what the sciences and the technology that flows from them have to offer, but we refuse to believe that we live in the world described by those very sciences.

Here I’m not merely talking about climate change deniers who, of course, fit this description. They merrily dial number after number on their cellphones, but they do so without realizing that in their climate change denial they are rejecting the very same science that underpins the phone they are using: physics.

But so many others live in this dual world as well. We humans imagine ourselves set apart from the natural world. And yet, our very bodies are the subject of scientific investigations. So we turn to our minds which we imagine set us apart from the natural world. But what is the mind? Do we not place the mind in the body? Are its manifestations not speech, writing, music, dance, and graphic arts which require the body for their expression.

The science of physics tells us that we live in a thermodynamic system. The universe is a thermodynamic system and so by definition must our Earth be one. Thermodynamic systems produce entropy, lots of it. Some two-thirds of all the energy we use in the United States is wasted. That’s right, wasted. That entropy shows up as climate-changing carbon dioxide in the atmosphere which is also acidifying the oceans. It shows up as barren landscapes left behind by coal and other mining. It shows up as waste heat and waste products flowing from our factories, our homes and our vehicles.

Did The EPA Just Go Rogue Again

Did The EPA Just Go Rogue Again

In late January, days after Donald Trump became president, various government workers employed by the EPA “defied” the president with what at the time appeared to be rogue twitter accounts emerging from the environemntal agency, most notably the Badlands National Park which slammed Trump’s climate change proposal.
  • “Today, the amount of carbon dioxide in the atmosphere is higher than at any time in the last 650,000 years. #climate”
  • “Flipside of the atmosphere; ocean acidity has increased 30% since the Industrial  Revolution. ‘Ocean Acidification” #climate #carboncycle’”
  • “Burning one gallon of gasoline puts nearly 20lbs of carbon dioxide into our atmosphere. #climate”

It now appears that a new “rogue” employee may have emerged at the EPA’s pres office.

This morning, in a press release summarizing “What They Are Saying About President Trump’s Executive Order On Energy Independence”, as the first quote picked by an unknown staffer at the agency, the EPA decided to showcase the thoughts of Dem. Senator Shelly Moore Capito whose quote was not exactly on message, as Bloomberg’s Patrick Ambrosio pointed out.

This is what she said:

With this Executive Order, President Trump has chosen to recklessly bury his head in the sand. Walking away from the Clean Power Plan and other climate initiatives, including critical resiliency projects is not just irresponsible — it’s irrational. Today’s executive order calls into question America’s credibility and our commitment to tackling the greatest environmental challenge of our lifetime. With the world watching, President Trump and Administrator Pruitt have chosen to shirk our responsibility, disregard clear science and undo the significant progress our country has made to ensure we leave a better, more sustainable planet for generations to come.

Toward a More Reflective Planet

Toward a More Reflective Planet

CAMBRIDGE – The last time the atmosphere held as much carbon dioxide as it does today was about three million years ago – a time when sea levels were 10-30 meters higher than they are now. Climate models have long struggled to duplicate those large fluctuations in sea levels – until now. Indeed, for the first time, a high-quality model of Antarctic ice and climate has been able to simulate these large swings. That is smart science, but it brings devastating news.

The new model shows that melting in Antarctica alone could increase global sea levels by as much as one meter (3.2 feet) by the end of this century – well above prior estimates. Worse, it suggests that even extraordinary success at cutting emissions would not save the West Antarctic Ice Sheet, locking in eventual sea-level increases of more than five meters. As little as one meter could put at risk entire cities, from Miami to Mumbai, and cause enormous economic disruption.

We need to turn down the heat – and fast. To this end, albedo modification – a kind of geoengineering intended to cool the planet by increasing the reflectivity of the earth’s atmosphere – holds tremendous promise.

Injecting synthetic aerosols that reflect sunlight into the stratosphere, for example, could help counter the warming caused by greenhouse gases. The mechanism is similar to wearing a white shirt in the summer: white reflects sunlight and cools what is underneath, whereas darker colors absorb sunlight and heat.

To be sure, even in the best-case scenario, solar geoengineering alone could not stabilize the world’s climate. For that, we must both stop pumping carbon pollution into the atmosphere and learn how to remove what is already there. That is why emissions cuts should receive the lion’s share of resources devoted to combating climate change.

Top Obama Energy Official Says Administration Rejects “Keep It In The Ground” As Climate Strategy

Top Obama Energy Official Says Administration Rejects “Keep It In The Ground” As Climate Strategy

We’re certainly not advocating any strategy for reducing hydrocarbon emissions by keeping oil in the ground…that’s not a position.”

This was the response of Christopher A. Smith when he was asked what he thought of the “growing movement of keeping oil in the ground” at the 2016 Columbia Global Energy Summit in April.

Since Chris Smith worked for more than a decade for Chevron and Texaco, this answer should not surprise anyone.

However, Chris Smith now works for President Obama as assistant secretary of fossil energy, so when he says “we’re certainly not advocating” he is referring to the fact that the Obama Administration’s Department of Energy does not support any strategy to keep oil in the ground.

And if you think Mr. Smith isn’t in a position of authority in the Obama administration when it comes to oil policy, you might want to consider how he was introduced at the event by moderator Antoine Halff:

[Smith is] Assistant secretary of energy for fossil fuels since 2014 but really at the heart of R&D and policy development issues since the beginning of the first Obama administration. And Chris has had a huge role in the government’s embrace of tight oil and shale, their benefits and the opportunities they represent…after perhaps a somewhat lukewarm start early in the first Obama administration.”

So according to Halff, who came to Columbia’s Center on Global Energy Policy from a position as chief oil analyst at the International Energy Agency, Chris Smith was instrumental in getting the Obama administration to “embrace” fracking for oil. And Smith is now saying that same administration certainly does not advocate keeping any oil in the ground.

Shrimps sound ocean acidity alarm

CROP--snapper shrimp

The effect of the sea absorbing increased carbon dioxide in the air has damaging consequences for the noisy snapping shrimp and marine life in coastal rock pools.

LONDON, 6 April, 2016 – The slow change in water chemistry as more and more atmospheric carbon dioxide dissolves in the sea and causes acidification could make the oceans much less noisy and slow the growth of life at the sea’s margins.

In one study, Australian scientists warn that as the acidity levels grow, the snapping shrimp may grow ever quieter. And in another study, Californian scientists have tested the water chemistry in coastal rock pools and discovered that they become most corrosive at night.

The snapping shrimp is the loudest invertebrate in the ocean. It forms bubbles in its snapping claw and uses this noise-making tool to warn off predators. And it can generate up to 210 decibels of noise, with important consequences for other creatures in coastal ecosystems.

Cracking sounds

“Coastal reefs are far from being quiet environments – they are filled with loud cracking sounds,” says Tullio Rossi, a marine acidification specialist at the University of Adelaide’s School of Biological sciences. “Shrimp choruses can be heard kilometres offshore and are important because they aid the navigation of baby fish to their homes. But ocean acidification is jeopardising this process.”

He and colleagues report in the Proceedings of the Royal Society B that they tested the shrimps under laboratory conditions of acidity predicted for the end of the century, and they found that both the frequency and volume of the snapping noises diminished.

The researchers also made field recordings at carbon dioxide-rich submarine volcanic vents, and observed the same pattern. They believe that the change of ocean pH levels affects behaviour, rather than impairing physiology.

Despite the world’s politicians finally agreeing, in Paris in December 2015, on what to do about global warming, many scientists still reject the evidence for it being caused by humans, or question that it is a significant problem.

For example, Dr Lindzen (2016) agrees that although carbon dioxide (CO2) is a greenhouse gas, which absorbs and re-emits infrared radiation from the Earth’s surface, the increase in its concentration in the atmosphere is not important because its climate sensitivity (the amount by which temperature will rise for a doubling of CO2) is low.

The problem with a carbon tax in Canada

The problem with a carbon tax in Canada

Catherine_McKennaLast week, Environment Minister Catherine McKenna indicated the federal government has not yet determined the national minimum carbon price which is part of its climate strategy. McKenna rejects any assertions the current economic environment is not the time to impose carbon pricing.

Frédéric Bastiat (1850) forewarned of demagogues like McKenna who demand the use of force to substitute their own inclinations for those of the human race. To seek support for her position, Minister McKenna is appealing to popular desires and prejudices using the most benign language conceivable. Using economic principles to unpack her message reveals its manipulative and sinister nature.

For decades, buyers and sellers have been peacefully discovering mutually agreeable prices for pieces of pure, crystalized carbon, more commonly known as diamonds.  If she chose, the Minister could walk in to any reputable jewelry store and survey the asking prices of diamonds which relate to the weight, shape, colour and clarity of the crystalized carbon. But this is not the carbon she has in mind that requires a national minimum price.

Instead the focus is carbon dioxide, a gas produced by all aerobic organisms when they metabolize carbohydrate and lipids to produce energy by respiration. It is also produced as organic materials decay, as sugars ferment in bread, beer and wine making and though the combustion of wood and fossil fuels such as coal, peat, petroleum and natural gas.

Carbon dioxide is a versatile industrial material. It is used as an inert gas in welding and fire extinguishers, as a pressurizing gas in air guns and oil recovery. It is added to drinking water and carbonated beverages including beer and champagne to add sparkle. As a liquid it is used a solvent in decaffeination of coffee and as dehydration agent. In solid form it is used as a refrigerant, a solvent and an abrasive.

Tomgram: Bill McKibben, It’s Not Just What Exxon Did, It’s What It’s Doing

Tomgram: Bill McKibben, It’s Not Just What Exxon Did, It’s What It’s Doing

The time scale should stagger you.  Just imagine for a moment that what we humans do on this planet will last at least 10,000 more years, and no, I’m not talking about those statues on Easter Island or the pyramids or the Great Wall of China or the Empire State Building.  I’m not talking about any of our monumental architectural-cum-artistic achievements.  Ten thousand years from now all the monuments to our history may be forgotten ruins or simply obliterated, while what we’re doing at this very moment that’s truly ruinous may outlast us all.  I’m thinking, of course, about the burning of fossil fuels and the sending of carbon dioxide (and other greenhouse gases) into the atmosphere.   It’s becoming clearer by the month that, if not brought under control relatively quickly, this process will alter the global environment in ways that will affect humanity and everything else living on this planet for what, from a human point of view, is eternity.

In essence, there’s no backsies when it comes to climate change.  Once you’ve begun the full-scale destabilization and melting of the Greenland ice sheet and of the vast ice sheets in the Antarctic, for instance, the future inundation of coastal areas, including many of humanity’s major cities, is a foregone conclusion somewhere down the line.  In fact, a recent study, published in the journal Nature Climate Change by 22 climate scientists, suggests that when it comes to the melting of ice sheets and the rise of seas and oceans, we’re not just talking about how life will be changed on Planet Earth in 2100 or even 2200.  We’re potentially talking about what it will be like in 12,200, an expanse of time twice as long as human history to date.

More warming will bring a more polluted future

More warming will bring a more polluted future

Global warming wil increase airborne aerosols and cause more atmospheric pollution, scientists say.

LONDON, 15 November, 2015 – The future is slightly obscured. The outlook is less than clear. For once, such phrases are not metaphorical.

A world of global warming could mean a growing haze of solid and liquid aerosols – tiny specks of salt, fine dust, sulphates, black carbon and other particles in the atmosphere, according to new research.

Robert Allen, an earth scientist at the University of California, Riverside and colleagues report in Nature Climate Change that as the planet warms because of greater concentrations of carbon dioxide and other greenhouse gases in the atmosphere, driven by ever greater human burning of fossil fuels, so too the air could become more murky.

Aerosols happen naturally and because of human activity. They are exquisitely small blobs of liquid or solid afloat in the atmosphere, the product of dust storms, plant pollen, wildfires, kitchen fires, smoke from factory chimneys and vehicle exhausts, volatile discharges from forests and so on. They may make humans cough or choke, and they exact a long-term toll on human health, but they also affect the climate.

Increase inevitable

These aerosols both scatter sunlight and absorb it, and climate scientists who try to model the future must also calculate the impact of aerosols on global warming: will these reflect or screen out solar radiation to slow down the process, or accelerate it?

Dr Allen and his colleagues turned the question around: what will increasing average levels of planetary temperature do for aerosols? The latest and most up-to-date climate computer simulations delivered the answer. Warmer means more haze.

“Our work on the models shows that nearly all aerosol species will increase under greenhouse gas-induced climate change,” Dr Allen said. “This includes natural aerosols like dust and sea salt, and also anthropogenic aerosols like sulphate, black carbon and primary organic matter.

As CO2 Levels Rise, Obama Still All Talk And No Action

As CO2 Levels Rise, Obama Still All Talk And No Action

After joining Facebook last week, the President used his very first video post to address the issue of climate change. The President said in the video: “Now, we’ve made a lot of progress to cut carbon pollution here at home, and we’re leading the world to take action as well. But we’ve got to do more. In a few weeks, I’m heading to Paris to meet with world leaders about a global agreement to meet this challenge.”

While the President’s detractors attacked him for believing something so foolish, the people who have been paying attention to Obama’s actions in recent years have an entirely different, and legitimate, reason to question the President’s message. Namely, President Obama has done very little to fulfill his lofty promises about tackling climate change.

Yes, we got a rule from the EPA to limit emissions from coal-fired power plants. Yes, the Keystone XL pipeline has been rejected (for now.) And yes, we finally have a President of the United States that both accepts the science of climate change and believes that we should do something about it. But that’s roughly where the accomplishments end.

As President Obama was recording his urgent Facebook plea to act on climate change, a new report came out that received far less fanfare than the President’s social media prowess. This new report, from the World Meteorological Organization (WMO), tells us that global CO2 emissions hit record highs in 2014, and that 2015 is on track to at least match those same levels.

2% Solutions for the Planet

2% Solutions for the Planet

Since we live in an era of big problems, we tend to spend our time thinking of big solutions. Thinking big, however, can have a paralyzing effect on taking action.

In my new book Two Percent Solutions for the Planet, I take readers on a journey around the world where low-cost, easy-to-implement solutions are regenerating the planet now, rather than in some distant future.

Two Percent Solutions for the Planet profiles fifty innovative practices that soak up carbon dioxide in soils, reduce energy use, sustainably intensify food production, and increase both water quality and quantity. Why “two percent? It is an illustrative number meant to stimulate our imaginations. It refers to: the amount of new carbon in the soil needed to reap a wide variety of ecological and economic benefits; the percentage of the nation’s population who are farmers and ranchers; and the low financial cost (in terms of GDP) needed to get this work done.

Big solutions, in other words, can be accomplished for small costs. They are solutions that are regenerative over the long haul, meaning they replete rather than deplete people, animals, plants, soil and other natural resources. See: http://www.chelseagreen.com/two-percent-solutions-for-the-planet

From the Prologue:

We live in an era of seemingly intractable challenges: increasing concentrations of carbon dioxide (CO2) in the atmosphere, rising food demands from a human population that is projected to expand from seven to nine billion people by 2050, and dwindling supplies of fresh water, to name just three. What to do? So far, our response to these big problems has been to consider “big” solutions, including complex technologies, arm-twisting treaties, untested geoengineering strategies, and new layers of regulation, all of which have the net effect of increasing complexity (and anxiety) in our lives. And most of these big solutions come with big costs, both financial and social, especially for those least able to bear them.

Exxon’s Own Research Confirmed the Role of Fossil Fuels in Global Warming Decades Ago

Exxon’s Own Research Confirmed the Role of Fossil Fuels in Global Warming Decades Ago

Minale Tattersfield / CC BY 2.0

Oil giant Exxon conducted cutting-edge climate research in the 1970s, and then, without disclosing the findings of its scientists, worked to manufacture doubt about the scientific consensus of its own research.

A groundbreaking investigation shows how the company’s top executives were warned of possible catastrophe from global warming, then led efforts to block solutions.

InsideClimate News explains:

At a meeting in Exxon Corporation’s headquarters, a senior company scientist named James F. Black addressed an audience of powerful oilmen. Speaking without a text as he flipped through detailed slides, Black delivered a sobering message: carbon dioxide from the world’s use of fossil fuels would warm the planet and could eventually endanger humanity.

“In the first place, there is general scientific agreement that the most likely manner in which mankind is influencing the global climate is through carbon dioxide release from the burning of fossil fuels,” Black told Exxon’s Management Committee, according to a written version he recorded later.

It was July 1977 when Exxon’s leaders received this blunt assessment, well before most of the world had heard of the looming climate crisis.

A year later, Black, a top technical expert in Exxon’s Research & Engineering division, took an updated version of his presentation to a broader audience. He warned Exxon scientists and managers that independent researchers estimated a doubling of the carbon dioxide (CO2) concentration in the atmosphere would increase average global temperatures by 2 to 3 degrees Celsius (4 to 5 degrees Fahrenheit), and as much as 10 degrees Celsius (18 degrees Fahrenheit) at the poles.  Rainfall might get heavier in some regions, and other places might turn to desert.

“Some countries would benefit but others would have their agricultural output reduced or destroyed,” Black said, in the written summary of his 1978 talk.

Nonlinear: New York, London, Shanghai underwater in 50 years?

Nonlinear: New York, London, Shanghai underwater in 50 years?

Those under the impression that climate change is advancing at a constant and predictable rate don’t understand the true dynamics of the issue. The rate of increase of the carbon dioxide concentration in the atmosphere, the main driver of climate change, went from 0.75 parts per million (ppm) per year in 1959 to about 1.5 ppm each year through the 1990s, to 2.1 ppm each year from 2002 to 2012, and finally to 2.9 ppm in 2013.

The fear is that the ability of the oceans and plants to continue to absorb half the carbon dioxide human civilization expels into the atmosphere each year may have become impaired. That means more carbon dioxide is remaining in the atmosphere where concentrations are building at the fastest rate ever recorded in the modern era.

Permafrost across the most northern reaches of land on the globe wasn’t expected the start melting until well into this century. Scientists were shocked to find gaping craters in Siberia where permafrost apparently is no longer permanent. It means carbon dioxide and methane–which absorbs about 80 times as much heat as carbon dioxide during its first 20 years in the atmosphere–will be unleashed from the melting permafrost much sooner than anticipated after being trapped for thousands of years. The release has the potential to speed up warming considerably.

Now comes what must be labeled as the most important story of the year that shows us yet more nonlinear dynamics in the world climate system. New research from James Hansen, the world’s most renown climate scientist, and 16 of his colleagues concludes that many of the world’s coastal cities could become “uninhabitable” in just 50 years due to a rapid, nonlinear rise in sea level. This is far sooner than previous findings suggested.

We May Have Already Committed Ourselves to 6-Meter Sea-Level Rise

We May Have Already Committed Ourselves to 6-Meter Sea-Level Rise

Even if humanity were to stop throwing carbon dioxide and methane into the atmosphere today, a catastrophic rise in sea levels of six meters may be inevitable. Two previous prehistoric interglacial periods, in which the carbon dioxide content of the atmosphere was believed to be about what it is today, resulted in dramatic rising of the oceans.

High-latitude ice sheets are melting, and given that global warming is most pronounced in the Arctic, it may already be too late stop a rise in sea levels that would flood out hundreds of millions around the world. Two new papers, the latest in a series of scientific studies, paint a picture considerably less rosy than conventional ideas that major damage can still be avoided.

One of these papers, a nine-scientist report led by geologist Andrea Dutton at the University of Florida published in the journal Science, found that modest rises in global temperatures in the past led to sea levels rising at least six meters. She summarized the findings this way to Climate Central:

“Even if we meet that 2°C target, in the past with those types of temperatures, we may be committing ourselves to this level of sea level rise in the long term. The decisions we make now about where we want to be in 2100 commit us on a pathway where we can’t go back. Once these ice sheets start to melt, the changes become irreversible.”

Professor Dutton was referencing the widely held belief that catastrophic damage can be avoided if global warming is held to no more than 2 degrees C. from pre-industrial levels. The “permissible” level may be less than that, however. More sophisticated “sea-level reconstructions” through interdisciplinary studies of geological evidence and better understanding of the behavior of ice sheets enabled the paper’s authors to infer that temperatures only slightly higher than what we are experiencing today upset the climatic balance. A summary of the paper concludes:

Recession, Not Fracking, Behind Drop in U.S. Carbon Dioxide Emissions, Scientists Conclude

Recession, Not Fracking, Behind Drop in U.S. Carbon Dioxide Emissions, Scientists Conclude

It’s been a talking point for boosters of the shale gas rush for years: as fracking spread across the country and the supply glut drove prices down, utilities have been shuttering dirty coal plants and burning natural gas instead – meaning that America’s carbon dioxide (CO2) emissions dropped sharply. Fracking, the argument went, is actually good for the environment because it’s good for the climate.

The boom in American natural-gas production is doing what international negotiations and legislation couldn’t: reducing U.S. carbon-dioxide pollution,” Bloomberg reported in 2012.

While other factors, including a sluggish U.S. economy and increasing energy efficiency, have contributed to the decline in carbon emissions from factories, automobiles and power plants, many experts believe the switch from coal to natural gas for electricity generation has been the biggest factor,” said the Wall Street Journal in April 2013.

“In these last years, the natural gas revolution, shall we say, has been a major contributor to reducing carbon emissions,” the Obama administration’s Department of Energy Secretary Ernest Moniz said at Columbia University on Aug. 26, 2013, as he described the President’s goals for reducing carbon emissions. “We are about halfway there, and about half of that is because of the substitution of natural gas for coal in the power sector, essentially driven by market forces.”

But, it turns out, correlation is not the same thing as causation. And while the drop in emissions happened at roughly the same time as the fracking rush spread, shale gas had relatively little to do with the drop in carbon emissions, according to a scientific paper published today in the journal Nature Communications.

Before 2007, rising emissions were primarily driven by economic growth,” ecological economist Dr. Klaus Hubacek and his fellow researchers wrote. “After 2007, decreasing emissions were largely a result of economic recession with changes in fuel mix (for example, substitution of natural gas for coal) playing a comparatively minor role.”
